Abstract
In accordance with the present invention there is disclosed a toy bicycle that includes a rear wheel assembly rotatably connected to the bicycle. The rear wheel assembly encloses a flywheel and a means of interconnecting the flywheel and the rear wheel. The interconnecting means serves to energize the flywheel in response to a rotational force applied to the rear wheel and when the rotational force is removed the interconnecting means will continue to rotate the rear wheel in response to the inertia of the energized flywheel. An articulated rider, mounted to the seat of the bicycle, includes hands rotatably attached to handlebars and feet attached to pedals of the bicycle. When the bicycle is in motion, the articulated rider appears to pedal and operate the bicycle. The bicycle also includes a charger that engages and rotates the rear wheel of the bicycle and as such, energizes the flywheel.
Description
FIELD OF THE INVENTION
This invention relates to a flywheel powered bicycle with an articulated rider, of which the flywheel may be energized with an external charger, and of which the articulated rider appears to be operating the bicycle when the bicycle is in motion.
BACKGROUND OF THE INVENTION
Flywheels and inertia wheels utilized in toy vehicles are well known. For example: U.S. Pat. No. 4,201,011 to Cook discloses a flywheel toy motorcycle that includes the flywheel about the front end of the frame. The motorcycle also includes a cord that when pulled energizes the flywheel, which will rotate independently of the rear wheel. The motorcycle further includes a clutch that places the flywheel in engagement with a gear train that rotatably attaches to the rear wheel, such that when the flywheel is rotating and the clutch is moved to such a position, the flywheel engages the gear train and rotates the rear wheel.
In addition, U.S. Pat. No. 3,886,682 to Iede discloses a flywheel-powered toy motorcycle, which mounts the flywheel within the front portion of the frame. The flywheel is meshed through a series of gears to an end gear rotatably attached to the rear wheel and an external launcher may be meshed with the end gear to energize the flywheel.
Flywheel-powered toy vehicles, which include two, three or four wheeled vehicles, are well known and generally include a gear train that is designed to charge the flywheel to a RPM significantly faster than the vehicle initially, such that when the vehicle is released the inertia of the flywheel will propel the vehicle quickly and for a significant distance. Normally the flywheel and gear train are housed within the chassis of the vehicle, thereby preventing damage to an exposed flywheel or injury to the user. Since the flywheel and gear train are placed in a housing, the manufacturer will design or mold a housing that represents a vehicle or toy that the user can visually relate to, for instance, a car or motorcycle. In such toys, the manufacturer can easily house the flywheel and gear train in the chassis of the car or in the center of the motorcycle frame.
A bicycle, however, has an open frame that does not provide any enclosure that may house the flywheel. In order to accommodate the flywheel and gear train, the bicycle must position or place the same about one of the wheels; otherwise the appearance of the open frame of the vehicle would be lost. The ability to place the flywheel and gear train about the front wheel is well known, U.S. Pat. No. 2,829,467 to Pagano discloses a toy motorcycle that includes a flywheel rigidly secured on a shaft, and housed within a hollow front wheel, which is mounted on the shaft for independent rotation relative to the shaft and the flywheel. A cord wrapped around the end of the shaft and rapidly pulled off, spins the flywheel within the front wheel. When the motorcycle is placed on a flat surface, friction between the wheel hub and the front axle causes the wheel to propel the motorcycle. Since the flywheel may rotate faster than the front wheel, the flywheel also acts as a gyro for stabilization.
In toys powered by a flywheel, especially two wheel toy vehicles, the flywheel is used to balance the two-wheeled vehicle. While the vehicle is in motion, any number of things can upset the vehicle's stability causing the same to lean and fall to one side, for example, while moving over a flat surface, any imperfections in the surface could upset the balance and stability. In order to compensate for this the vehicle can be provided with caster steering. However, when the flywheel is enclosed within the front wheel, caster steering is removed in order to accommodate for the flywheel and gear train. As such it would therefore be desirable to place the flywheel in the rear wheel.
While full size bicycles have been provided in the past with a flywheel in the rear wheel of the bicycle, for instance U.S. Pat. No. 639,567, the person operating the bicycle powers the flywheel by pedaling the bicycle. More importantly, the person provides the needed stability and balance to keep the full size bicycle upright. In U.S. Pat. No. 639,567 the flywheel is only used to assist the power provided by the operator to help coast the bicycle and cannot aid in balancing or stabilizing the bicycle upright.
Generally, when a flywheel spins it creates a gyro effect on the bicycle itself, acting thereon to balance the bicycle. This effect is proportional to the difference in weight between the flywheel and the bicycle, such that when the weight of the flywheel is larger than the weight of the bicycle, the gyro effect will be greater. To the same extent, a real bicycle would include the weight of the person and bicycle, which would significantly outweigh the flywheel, unless the flywheel was extremely large or heavy, which is impractical. In toys the material used to manufacture the bicycle and rider, such as foam or plastics, can have a total weight much lighter than the weight of the flywheel and still visually appear proportional to each other. As such, a toy bicycle can have a small flywheel that produces a gyro effect on a light weight bicycle that aids in the stability and balance of the bicycle.
SUMMARY OF THE INVENTION
In accordance with the present invention there is disclosed a toy bicycle that includes a rear wheel assembly rotatably connected to the frame of the toy bicycle. The rear wheel assembly has a two-piece rear wheel that encloses a flywheel and a means of interconnecting the flywheel to the rear wheel housing such that the flywheel may rotate independently about the same axis as the rear wheel. Moreover, the interconnecting means provides the ability to energize the flywheel in response to an external rotational force applied to the rear wheel and when the external rotational force is removed the interconnecting means will continue to rotate the rear wheel in response to the inertia of the energized flywheel. The toy bicycle further includes a rear pulley simulating a sprocket (referred to herein as a “rear sprocket”) that is secured to the rear wheel such that when the rear wheel rotates, the rear sprocket also rotates. The rear sprocket is further attached to a pedal/crank/sprocket assembly that is horizontally and rotatably mounted to the frame, such that the rotation of the rear sprocket further rotates the pedal/crank/sprocket assembly. An articulated rider, mounted to the seat of the bicycle, has hands attached to the handlebars and has feet attached to pedals defined by the pedal/crank/sprocket assembly. When the pedal/crank/sprocket assembly rotates, the articulated rider having joints positioned in the legs appears to pedal the pedal/crank/sprocket assembly and as such the articulated rider appears to be operating the bicycle.
In one embodiment, the bicycle further includes the means to energize the flywheel through an external charger. The external charger is motorized such that the user can hold on to the bicycle and energize the flywheel effortlessly. After the flywheel is energized, the user can easily remove the external charger, place the bicycle on a surface and watch it drive away. In yet another embodiment the flywheel may be energized in an external launcher that includes a mechanical charger. The user places the bicycle in the launcher and begins to mechanically charge the flywheel by rotating the rear wheel. When flywheel is sufficiently energized, the user stops mechanically rotating the rear wheel. However, the energized flywheel will continue to rotate the rear wheel such that the bicycle automatically propels itself out of the launcher.
Numerous other advantages and features of the invention will become readily apparent from the following detailed description of the invention and the embodiments thereof, from the claims, and from the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION
While the invention is susceptible to embodiments in many different forms there are shown in the drawings and will be described herein, in detail, the preferred embodiments of the present invention. It should be understood, however, that the present disclosure is to be considered an exemplification of the principles of the invention and is not intended to limit the spirit or scope of the invention and/or claims of the embodiments illustrated.
Illustrated in FIG.
1
and in accordance with the present invention, a flywheel bicycle
10
is provided that includes an articulated rider
12
, which when the bicycle is in motion, visually appears to be pedaling the bicycle
10
and thus appears to be operating the bicycle. A flywheel (not shown) is included in the rear wheel
16
of the bicycle
10
, which may be energized by a user h holding on to the bicycle
10
and continually pushing or rotating the rear wheel forward, or exerting an external rotational force upon the rear wheel
16
. Once the flywheel is sufficiently energized the user may stop rotating the rear wheel
16
and release the bicycle
10
. The inertia of the flywheel will thereafter cause the rear wheel
16
to continue to rotate, powering and balancing the bicycle
10
forward.
In addition, a pedal/crank/sprocket assembly
18
, discussed in further detail below, is attached by a belt
90
to the rear wheel
16
such that the rotation of the rear wheel
16
also rotates the assembly
18
. The articulated rider
12
includes hands
23
that are rotatably attached to a handlebar assembly
70
and includes feet
50
that are separately attached to the pedal/crank/sprocket assembly
18
. When the bicycle is in motion, the pedal/crank/sprocket assembly
18
rotates, moving the legs of the articulated rider
12
and providing the visual appearance that the rider
12
is pedaling and powering the bicycle
10
.
As illustrated, the flywheel is positioned or housed in the rear wheel
16
providing the ability to maintain the visual representation of a bicycle. In addition the front end
62
of the bicycle includes a caster steering
63
, which aids the flywheel in balancing the bicycle upright, because if the bicycle
10
were to begin to lean to one side the caster steering
63
would cause the bicycle
10
to turn opposite of the direction of the lean leveling the bicycle
10
.
Moreover, if the flywheel was positioned in the front wheel it would be difficult to utilize the flywheel to rotate a pedal/crank/sprocket assembly, without attaching the pedal/crank/sprocket assembly to the front wheel. Since real bicycles attach the pedal/crank/sprocket assembly to the rear wheel, if in the instant invention the pedal/crank/sprocket assembly was attached to the front wheel, the invention would no longer accurately and visually represent a bicycle.
Further reference is now drawn to
FIG. 2
, which is an exploded view of the flywheel bicycle
10
with the articulated rider
12
. The articulated rider
12
includes a torso
20
jointed to two arms
22
and to two upper leg portions
24
, wherein each upper leg portion
24
is further jointed to a lower leg portion
26
. The arms
22
are jointed to the torso
20
at a shoulder joint
30
, which permits the arms to pivot about a shoulder joint pin
34
. The shoulder joint
30
includes a pair of joint plates
32
that individually secure into the arm
22
and the torso
20
, and the shoulder joint pin
34
positioned there through further prevents the arm
22
from separating from the torso
20
. The upper leg portions
24
are jointed to the torso at a hip joint
36
, which permits the upper leg portion to pivot about a hip joint pin
40
. Each hip joint
36
includes a pair of joint plates
38
that are individually secured into the upper leg portion
24
and the torso
20
, with the hip joint pin
40
positioned there through further preventing the upper leg portion
24
from separating from the torso
20
. The upper leg portions
24
are also jointed to lower leg portions
24
by a knee joint
42
, which permits the lower leg portions
24
to pivot about a knee pin
48
. A clevis end
44
on the upper leg portion
24
that is sized to receive an end
46
of the lower leg portion
26
defines each knee joint
42
. The upper leg portion
24
and lower leg portion
26
are pivotally secured together by the pin
48
positioned through the clevis end
44
and the end
46
on the lower leg portion
26
. The lower leg portions
26
further include feet
50
, which as described in further detail below attach to pedals
82
on the bicycle
14
.
The bicycle
10
has a frame assembly that permits the attachment of a seat assembly, a handlebar assembly, a pedal/crank/sprocket assembly and a front and rear wheel assembly. More specifically, the bicycle
10
includes a frame
52
that includes a tubular portion
54
, which is designed to receive one end of a seat post
56
. The other end of the seat post
56
securely receives a seat
58
, which includes a projection
59
that is securely received in a slot
39
on the lower portion of the torso
20
, thereby securing the articulated rider
12
to the seat
58
. The seat post
56
further receives a plate
60
that the user h may grab in order to energize the bicycle
10
, shown in FIG.
1
. The front end
62
of the bike
10
includes a tubular post
64
that secures a front fork
66
by a steering pin
68
. A handlebar assembly
70
, which includes handgrips
72
, attaches to the top portion of the front fork
66
through the tubular post
64
. When assembled, the hands
23
of the rider
12
rotatably attach to the handgrips
72
, providing the visual appearance that the rider
12
is steering the bicycle. Moreover, since the hands
23
may rotate, the rider
12
may be positioned in various stunt positions, such as placing the feet
50
on the seat
58
. Connected to the front fork
66
via its lower end by a front axle
74
is a front wheel
76
on which is located a tire
78
. In addition, a pair of foot pegs
75
may be attached to the front axle
74
and the rear axle
94
. The feet
50
of the articulated rider
12
may be moved to rest on the foot pegs
75
, thereby providing the articulated rider
12
with a coasting, resting or stunt position.
Secured to a horizontally disposed tubular support
80
at the midsection of the frame
52
is the pedal/crank/sprocket assembly
18
that will rotate along with the rear wheel
16
. The pedal/crank/sprocket assembly
18
includes pedals
82
, each of which include a peg
83
that engage the underside of each foot
50
, thereby securing each foot to a pedal
82
. Each pedal
82
is rotatably connected to a crank
84
that further attaches to a front sprocket
86
about a crank axle
88
that extends through the horizontal tubular support
80
. The front sprocket
86
is connected through a belt
90
(shown in
FIG. 1
) to a rear sprocket
92
, which is located about the rear axle
94
and described in greater detail below. In addition, attached to the rear end
98
of the frame
52
are a pair of launch pegs
114
that extend outwardly and substantially perpendicular from the frame
52
and are also described in greater detail below in reference to a launcher.
The rear wheel assembly includes a rear tire
96
disposed about the rear wheel
16
, which is rotatably attached to the rear end
98
of the frame
52
about the rear axle
94
. The rear wheel
16
is defined by a left and right flywheel housing
100
and
102
and includes an exterior launch gear
104
, which permits the bicycle
10
to be energized and launched by a separate launcher mechanism, discussed in greater detail below. The rear wheel assembly also has a power mechanism connected to the rear wheel
16
and mounted on said axle such that the power storage mechanism may store inertia energy in response to the rotation of the rear wheel
16
and may rotate the rear wheel
16
in response to the stored inertia energy. The power storage mechanism is housed within the flywheel housing
100
and
102
and is defined by a flywheel
106
and a means for interconnecting the flywheel
106
to the rear wheel
16
. The flywheel
106
is mounted for independent rotation about the same axis as the rear wheel
16
. The means for interconnecting the flywheel
106
to the rear wheel
16
is also enclosed within the flywheel
106
housings
100
and
102
. The interconnecting means serves to energize the flywheel
106
in response to an external rotational force applied to the rear wheel
16
and when the external rotational force is removed the interconnecting means continues to rotate the rear wheel
16
in response to the inertia of the energized flywheel
106
. The interconnecting means is defined by the flywheel being independently mounted to the right flywheel housing
102
and meshed to a gear plate
108
that is further meshed to an internal gear
112
through a series of gears
110
. The internal gear
112
is attached to the left flywheel housing
100
.
The rear sprocket
91
is secured to the right flywheel housing
102
and rotates the front sprocket
86
, via the belt
90
, when the rear wheel
16
is rotating. The rotation of the front sprocket
86
, as mentioned above, turns the cranks
84
and the pedals
82
, causing the articulated rider
12
to appear as if it was pedaling and operating the bicycle
10
.
In operation the external rotation of the rear wheel
16
, causes the internal gear
112
to rotate or energize the flywheel
106
. Once the external rotation stops, the energized flywheel
106
continues to rotate the internal gear
112
, which will rotate the rear wheel
16
, as long as the inertia of the energized flywheel
106
continues to power the internal gear
112
. By mounting the flywheel
106
independently about the same axis as the rear wheel
16
and meshing the flywheel
106
to the interconnecting means within the rear wheel
16
, the flywheel
106
, when spinning causes a gyroscopic effect that helps keep the bicycle
10
vertical.
As described briefly above, the flywheel
106
of the bicycle
10
may be mechanically charged and launched from an external launcher, such as the one illustrated in
FIGS. 3-6
. As illustrated in
FIG. 6
, the launcher
120
includes a drive gear
142
that partially protrudes from an aperture
121
on the topside of the ramp
122
. The drive gear
142
is secured to a crank gear
138
on a launch axle
140
. Both the drive gear
142
and the crank gear
138
rotatably rest in supports
144
that extend upwardly from the base
146
of the launcher
120
. The drive gear
142
is meshed to a crank wheel
136
that is rotatably housed within two halves
132
,
134
of a crank wheel housing
130
. The crank wheel housing
130
is secured to the ramp
122
through an opening
135
on the side of the launcher
120
. A crank handle
128
may be used to rotate the crank wheel
136
, which further rotates the drive gear
142
. The launcher
120
also includes a pair of guide walls
124
each of which includes a notch
126
.
In
FIG. 3
a
the bicycle
10
is shown entering the launcher
120
, while in
FIG. 3
b
the bicycle
10
is positioned between the guide walls
124
. The launcher pegs
114
that extend outwardly from the rear end
98
of the frame
52
are positioned such that they may engage the notches
126
. When the bicycle
10
is in position as illustrated in
3
b
, the drive gear
142
engages the launch gear
104
. The crank handle
128
may be used to rotate the drive gear
142
and thus energize the flywheel
106
.
Illustrated in
FIGS. 4 and 5
, the bicycle
10
is shown in the launcher
120
. When the launcher pegs
114
are positioned in the notches
126
, the centerline of the rear wheel
16
aligns slightly aft of the centerline and of the drive gear
142
. As the drive gear
142
rotates, the rear wheel
16
begins to rotate thus energizing the flywheel
106
. While the inertia of the drive gear
142
is greater than the rotation of the rear wheel
16
the bicycle
10
will have a tendency to move backwards because the centerline of the rear wheel
16
is aft of the centerline and of the drive gear
142
, as such the bicycle remains in the launcher. However, as soon as the user stops or slows down the rotations of the drive gear
142
, the inertia of the energized flywheel
106
begins to rotate the real wheel
16
faster than the inertia of the drive gear
142
, causing the bicycle to automatically launch out of the launcher
120
.
In addition a motorized external charger
150
may also be used to energize the flywheel
106
, illustrated in
FIGS. 7 through 9
. The motorized external charger
150
houses a motor
152
that operatively controls a pinion gear
156
through a gear train
154
. The motor is powered by a pair of batteries
158
which may be removed from the bottom portion
159
of the motorized external launcher
150
. The pinion gear
156
passes through a socket
160
such that the pinion gear
156
may engage the launch gear
104
such that when the motorized external charger
150
rotates the pinion gear
156
the launch gear
104
rotates, energizing the flywheel
106
. The socket
160
acts to keep the pinion gear in engagement while the flywheel
106
is energizing. The user holding the bicycle
10
and the motorized external charger
150
places the pinion gear
156
into the socket
160
and then presses a switch
162
which turns the motor
152
on and off. Since the motorized external charger
150
is small and compact, the user is able to carry it around with them easily.
As described above, rotating the rear wheel
16
against a flat surface may also energize the flywheel
23
. As such the launcher/charger may be removed and the launch gear
104
and the launcher pegs
114
may be removed from the bicycle
10
without diverting from the scope of the present invention.
From the foregoing and as mentioned above, it will be observed that numerous variations and modifications may be effected without departing from the spirit and scope of the novel concept of the invention. It is to be understood that no limitation with respect to the specific methods and apparatus illustrated herein is intended or should be inferred. It is, of course, intended to cover by the appended claims all such modifications as fall within the scope of the claims.
